My thoughts are that CX will paint the un-finished paint part in the bottom in a few months to the regular look. I don't think it will last that long because it doesn't even look as if it was a special scheme.

Just to reiterate. Many comments on this photo seem to indicate that it is the 100th aircraft for the combined fleet if Cathay, Dragonair, and Air Hong Kong. Well cathay is larger than most people realise and this will be our 100th aircraft to join our fleet. This excludes Dragonair and Air Hong Kong which also operate a number of Airbuses.
